APPARATUS FOR SPRAYING PLANTS AND TREES.

Application filed November 1, 1926. Serial No. 145,471.

This invention relates to new and useful it wi h the material to be sprayed on the improvements in apparatus for treating plants and the valve 13 is opened. After plants, particularly cotton plants, to destroy passing through the pump the water is conand remove injurious insects, parasites and veyed through a pipe 1? and passes into the co 5 the like or to treat the plants for blight, contamcr 6 through a pipe 18. This pipe is etc. dlrccted along the side of the tank 6 and has One of the particular features of the inconnected to its lower end a curved tube 20. vention is to provide a machine of this class Thls tube, see Figure 4, has an opening in of as few parts as possible and by means of its free end at 21, the opening being rela- 05 10 which the plants may be treated cconomitwely small.

Obviously alterations and changes may be made in the construction of the invention as it is not to be understood as being limited to the particular construction here shown, such changes and alterations to come within the scope and meaning of the appended claim.

What is claimed is:

An apparatus of the class described, com- PllSlIlg a cylindrical tank for liquid to be sprayed, said tank having a pipe connected to the upper end thereof and extending downwardly to the lower part of the tank,

said pipe having on its lower end a curved tubular extension positioned adjacent to and conformin to the shape of the cylindrical wall of said tank, said extension being provided with a reduced opening to cause the liquid as it enters the tank to be moved circularly around the tank to mix and agitate the liquid and the poison contained therein, said curved tubular extension also having an openin at approximately its center to cause t e liquid to be forced in a radial direction across the central portion of the tank to prevent a sediment forming at the center of the tank and to maintain the liquid contents in an agitated and mixed condition.

In testimony whereof I aflix my signature.
